Now with this new update, pdf files always open in browser. In the previous version, even when configured in the settings, the file was downloaded from some websites when this was the case. In other words, the browser is not respecting the rule defined by the website itself of downloading the file and not opening it within the browser. Now, the files always opens in-browser, it's very annoying. It looks like it's a bug. Please fix it.

Try going to Tools -> Settings -> General and in the Applications area, set PDFs to Always Ask or whatever option you want to happen. Screenshot: https://i.imgur.com/kznL8PQ.png

A change was made several versions ago for 'local' pdf files which evidently extended to files on an intranet. Are you referring to an intranet? If so, you will have to change a preference in about:config.

PDF files now open in Firefox by default, even files served by the website with "Content-Disposition: attachment". See How file downloads are handled in Firefox version 98 and above.

it would be simpler if it was left as it was or at least had the option of leaving it as it was before, but apparently it doesn't. Apparently, a "non-issue" has been resolved in this update.

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or Firefox developers. If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
